MACHINE FOR MARKING AND LAYING OUT DIES.

SFEOIFICATION forming part of Letters Patent No. 773,896, dated November1, 1904.

Application filed June 11, 1903.

To all whom it may concern.-

Be it known that I, VVILLIAM J. RICHARDS, a citizen of the UnitedStates, and a resident of WVa-terbury, in the county of New Haven andState of Connecticut, have invented certain new and useful Improvementsin Machines for Marking and Laying Out Dies, of which the following is aspecification.

My invention relates to new and useful improvements in machines forlaying and marking out dies, templets, and the like.

It is the object of the invention to provide a machine which may beespecially adapted for the use of die-sinkers, tool-makers, or jewelerswhereby they are enabled to quickly and accurately mark out a die ortemplet, includ ing the locating and marking of centers, the inscriptionof straight, angular, and circular lines, all of which may be followedin marking the die; further, to adapt the machine for a large variety ofwork, including dies of different thicknesses and sizes, and toconstruct it in such a way that its usefulness will not be limited tothe laying out of dies, but to the laying out of other classes of workas, for instance, that of engraving; finally, to provide a machine witha fine adjustment and a system of graduations whereby accuracy isassured and whereby several dies of like or varying designs may bemarked out separately from a chart or memorandum without applying apattern to the work.

With the above and other minor objects in view my invention resides andconsists in the novel construction and arrangement of parts shown uponthe accompanying three sheets of drawings, forming a part of thisspecification, upon which similar characters of reference denote like orcorresponding parts throughout the several figures, and of which Figure1 shows a front elevation of my improved machine complete. Fig. 2 is atop or plan view of Fig. 1. Fig. 3 is a central vertical cross-sectiontaken on line 3 3 of Fig. 1; and Fig. 4: is a plan view of a die,representing in part some of the work for which my machine is designed.

Referring in detail to the numerals of reference marked upon thedrawings, 1 indicates 5 a bed, 2'legs for supporting the same, and 3Serial No. 161,030. (No model.)

standards or brackets of the bed, one of which is located at either sideof the rear of the machine. The bed is provided with a transverse Way4:, upon which is mounted a slide 5.-

This slide is provided with a central depending bracket 6 for theengagement of an adjusting-screw 7, which is journaled in the bed at oneand in a bracket 8 of thebed at the other end. A handle 9 is provided onthe outer end of this screw for rotating the same and adjusting theslide to and from the operator. A disk 10 is secured to the screw andturns with it. The periphery of said disk is further provided with aseries of graduations which in practice are preferably divided into verydesirable and accurate adjustment of the bed may be had by the simpleadjustment of the screw when operated in connection with the graduationsof the disk and pointer,

The top slide is provided with a pivotal hub 12, upon which is mounted arotatable stockcarryin'g table 13.

which the screws 15 on said table project to secure the same in place.This table may be at times rigidly secured to the slide, while at othersthe screws would be loosened to permit of its rotary adjustment thereonin order to swing the work around under. the pointer.

The slide referred to is provided with a bevel annular ledge 16, uponwhich is in-' scribed in proper order a series of graduations on each ofits two front quarters, said series reaching from front center to sideand representing one to ninety degrees, each set of graduationsindicating a quarter of a circle and the two combined a half-circle.These graduations are read in connection with a suit- Said hub 12 isprovided. with an annular groove 14, over which the depending flange ofthe table extends and into able indicating-line on the table, so thatthis l adjustment may be accurately determined with relation to theslide upon which it is mounted.

The table is further provided with a series of holes 18, by means ofwhich the die-block may be clamped to the table for the operationthereon of the marker 17, which is located above and which issusceptible of vertical, horizontal, transverse, and independentcircular movement, as will later be more fully explained.

The two standards or brackets 3, before mentioned, are provided withvertical ways 19, against which the cross-rail 20 is adjustably securedby means of studs and clamping-nuts 21, said standards being providedwith vertical grooves to accommodate the vertical movement of the studand cross-rail for said nut, as will be apparent from Fig. 3. On thiscrossrail is provided at either end a forwardly-disposed bearing 22,through which loosely pass vertical screw-posts 23, the same beingsecured to the bed of the machine and provided with a supporting-nut 24below said bearing 22 and a lock-nut 25 above the bearing. These nuts,as will be seen, are knurled to facilitate hand manipulation, wherebythey are run up and down on the screw to raise and lower the cross-railand the marking-tool carried thereby. These screws are further providedwith corresponding graduations 26, as shown in Fig. 1, so as to enablethe operator to adjust and set the two sides alike in order to keep thecross-rail horizontal. Upon this rail is slidably mounted an adjustablehead 27, which carries the marking-tool 17 before mentioned. Anadjusting-screw 28 is rotatably mounted in this cross-rail, beingprovided with an operating-handle 29 and graduated disk 30, the latterbeing read in connection with a pointer 31, as in the case of theadjusting mechanism for the die-carrying table and slide.

The head 27, which is mounted upon the rail, as before stated, carriesthe markingtool through the medium of an independentlyadjustable holderand carrier, which are movable vertically and laterally, besides beingrotatable independent of the before-mentioned head and adjustingmechanism. The holder 34. is pivoted to a shank 3 1, which snugly fitsinto a rectangular vertical hole of the head mounted upon the rail andis supported by a central adjusting-screw 32, having a knurled head 33.This head is graduated, as at 33, to be read in connection with the line33 on the head, and consequently the shank and holder may be raised andlowered by the rotation of this screw 32. The holder is provided with atransverse way and an adjusting-screw 35, which engages and operates theneedle-carrier 36, adjustably mounted upon the ways of the holder in amanner to permit of a slight transverse movement of the needle by theoperation of the screw 35 independent of the movement of the headmounted upon the rail to throw the needle off of the center for themarking of small circles.

From the foregoing it will be noted that the die to be operated upon issecured to the table, that the table is susceptible of both rotary andtransverse movement. In addition to this the head and marking-needle areeach provided with two independent horizontal and vertical movements,also circular movement for the needle. It is therefore possible by thetwo combined movements of the screws 7 and 28 to bring the needle overany portion of the surface of the die, and such position of the needlewhen so placed can be read upon the graduations of disks 10 and 30. Itis further true that when so placed the needle can be lowered in contactwith the work for marking the same. By the manipulation of the handle 29the needle can be carried directly across the die in a way to inscribe aline across the face of the same, or by the manipulation of the handle 9a line may be inscribed ata right angle to the before-mentioned line.The needle may also be used for inscribing small circles by adjustingscrew 35 to set the needle at a given point from beneath the center ofscrew 32 and then rotating the holder or slide of its pivot on part 34.Thus the needle will inscribe any circle or part of circle desired uponthe face of the die. If a series of cen ters is desired, as in the caseof those indicated in Fig. 4, it can be had by simply adjusting thescrews before mentioned a certain number of turns in accordance with thedesired distance between the centers whereupon they may be located, aswill be apparent.

The machine is quick of operation, accurate in its work, andparticularly desirable and convenient for the line of work for which itis designed.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, is
